Yogic conception allows sperm to travel more easily from the lingam to the yoni (dick to buttgina)
Yogic conception allows sperm to travel more easily from the lingam to the yoni and pregancy will be easier to attain in Yogic positions than in regular positions. Womb energy flows from the lingam to the yoni to the womb, from sperm to egg.
